Abstract: METHOD AND APPARATUS FOR PRODUCING NON-ABRASIVE COKE FORMS FROM BROWN COAL BRIQUETS                   ABSTRACT OF THE DISCLOSURE          The coke forms are produced in four stages, each consti-tuted by a respective oven chamber, and in which the briquets are, respectively, preheated, dehydrated or dried, carbonized and cooled.  Hot gas circuits are provided, in which the hot gas is composed substantially of burnt lean gas of the carboniza-tion, and, for each stage, the hot gases are recirculated in a separate respective circuit.  In the preheating, dehydrating and carbonization stages, the hot gases are heated and produced, or supplemented, in a respective separate combustion chamber with the recirculating hot gas in the carbonization stage being supple-mented with cooled lean gas from this stage.  The recirculating hot gases are dedusted separately in a dust settling chamber in which their flow velocity is reduced to approximately 0.2 to 2.0 m/sec, with the dust being collected.  Steam may be added to the recirculating hot gas of the preheating stage, drying stage, or both, and the pressure in the hot gas circuits is maintained at a level slightly higher than atmospheric pressure. The oven chambers are arranged as a vertical oven block plant and the oven chambers are interconnected with each other by transition zones which are conically  narrowed to approximately one half of the cross section of the chamber and then widened up to the full cross section.  The hot gas inlets are provided in the transition zones at the lower ends of the oven chambers, and the hot gas outlets are provided in the transition zones at the upper ends of the chambers.  The dust settling chambers are provided immediately adjacent the hot gas outlets, and the carbonization chamber is surrounded by its combustion chamber to form an operating unit.

Abstract: INVENTION:     TESTING VISCOELASTIC SOLIDS FOR ABILITY         TO WITHSTAND STRESS AND STRAIN            INVENTORS:     D. C. PREVORSEK, Y.D. KWON, R. K. SHARMA and E. T. GILLIAM                   Abstract of the Invention An apparatus and method for testing viscoelastic solids, such as tire cord, especially for ability to withstand stress and strain.  The apparatus includes:  a holding means, a pretension means, a displacement generator, and a mechanical-electrical transforming means.  The holding means holds the material in a predetermined position.  The pretension means applies tension during testing.  The displacement generator has an eccentric means for applying cyclic displacement.          The mechanical-electrical transforming means transforms mechanical motion into electrical signals, such as a stress signal, a strain signal and a differentiated strain signal.          There is a phase lag between the stress signal and the strain signal and the phase lag may vary in amount and direction as a function of time.  The apparatus may also include:  an integrating means for integration of a stress-strain hysteresis loop; and a display means for displaying an output of the integrating means to measure the area of the hysteresis loop and thereby determine energy loss.  The method includes: applying strain to the material, with resulting stress developed in the material; transforming the strain into an electrical strain signal having a strain wave form; transform-ing the resulting stress into an electrical stress signal having a stress wave form; controlling the strain to produce a substantially sinusoidal strain wave form representing strain;   and allowing the stress to produce a stress wave form represent-ing stress which may be non-sinusoidal or sinusoidal.

Abstract: A COMPUTER CONTROLLED PNEUMATIC                  RETRACTABLE SEARCH SENSOR                 ABSTRACT OF THE DISCLOSURE         A mechanical manipulator which includes fingers under the control of a computer  antenna sensing means mounted on such fingers and extended and retracted from the fingers under the control of the computer  means for detecting the contact or proximity of the extended antenna sensing means with a workpiece  means responsive to the antenna sensing means for retracting the sensing means from interference with the workpiece and for adjusting the control of the fingers.  The fingers are adapted for X  Y and Z linear motions and provides pitch  yaw and roll angular motion.  The retractable antenna sensing means resembles a whisker which extends from the finger and makes contact with or approaches the workpiece.  The antenna sensing means may include a retractable pneumatic back pressure sensor via the back pressure of a fluid in the supply  created when the fluid impinges on the workpiece.  The retractable antenna whisker bends more readily than the rigid finger.  Therefore  contact with an object will not cause displacement of the object as a rigid finger would.  Computer logic circuits receive signals representing the displacement and positions of both the antenna sensing means as well as the manipulator fingers and coordinates both sets of signals to determine the orientation and position of the workpiece and the shape of the workpiece.

Abstract: Docket 5810 METHOD AND APPARATUS FOR RECORDING A SINGLE VIDEO FRAME                   ABSTRACT OF THE DISCLOSURE            A disc recorder having a single magnetic pick-up and record head and having a magnetic disc, rotating at the frame rate of a video signal, records and provides for display a single frame from a video signal consisting of a series of video frames.  Motion jitter is eliminated by recording on the disc recorder one of the two fields which make up a chosen video frame and then reproducing this field.  The reproduced field signal is then stored and rerecorded onto the magnetic disc at a position relative to the original field recording corresponding to the delay between two interlaced fields.  A memory having less capacity than that required for storing a complete field signal is used with only a portion of a field being reproduced, stored and rerecorded during each rotation of the magnetic disc.  A complete video frame is thus recorded, ready for display, in which the two inter-laced fields are identical.

Abstract: STAB-TYPE JOINT FOR SMOOTH END OR FLARELESS PIPE     ABSTRACT OF THE DISCLOSURE         A joint for connecting a smooth wall pipe to fittings or other pipes, the joint including a hollow body member having a passageway therethrough, a split gripper ring positioned and movable axially within the passageway, an elastomeric sealing ring also positioned and movable axially within the passageway and means for axially urging the gripper ring and the sealing ring apart whereby the gripper ring has improved initial grip on the pipe upon insertion of the same and the sealing ring has improved sealing characteristics over a range of positive and negative pres-sures and over a hot and cold temperature range.  The external con-figuration of the split gripper ring cooperates with the internal configuration of the passageway so that the pipe can be installed axially into the body member but when pulled outwardly of the body member the gripper ring is further actuated from its initial grip-ping action to prevent removal of the pipe.  The sealing ring is provided with a load on the same at all times whereby it has an initial sealing function upon insertion of the pipe and also main-tains this sealing function despite subsequent disturbances of the sealing ring by movement of the pipe.  The means urging the seal-ing ring and the gripper ring axially apart also functions to make out of round pipe more round upon insertion so that the position of the sealing ring is not unduly disturbed from its seat.

Abstract: ABSTRACT OF THE DISCLOSURE           A valve convertor phase control device comprises a control signal forming unit, a reference signal unit, a sawtooth signal generator, a differential comparator, a phase limiting unit, a control pulse generator, and a pulse distributor.  Two inputs of the differential comparator are connected to the control signal forming unit and to the output of the sawtooth signal generator, while the output of the differential comparator is connected through the phase limiting unit to the input of the control pulse generator.  Pulses whose phase is determined by said control signal are formed at the output of the control pulse generator.  Control pulses are fed through the pulse distributor to the convertor valves.  The sawtooth signal generator has two inputs, the first of which is connected to the output of the control pulse generator and ensures that the sawtooth signal generator is in step with the network supplying current to the valve convertor and the other input of the sawtooth signal generator is connected, through a function generator, to the input of the control pulse forming unit and provides for a sawtooth signal transconductance curve.  The phase control device ensures that the operation parameters of the valve convertor precisely correspond to preset values and makes it highly effective in transient operating conditions.

Abstract: SOLAR RADIATION COLLECTION SYSTEMS      Abstract of the Disclosure High efficiency solar radiation collectors may employ a dual flow path relative to heat transfer surfaces of the collector panel.  A major air flow is confined beneath the panel, but a subsidiary (bypass) air flow at an angle to the principal air flow is also employed to suppress natural (free) flow convection at an upper side of the panel.  Advantageously, the subsidiary air flow can be established by perforations in the collector panel and by creation of a suction for the by-pass air.  High efficiency energy collection, particularly adapted to weak and intermittent radiation environments, is further enhanced by the usage of a collector panel having a low thermal mass and providing good thermal interchange with a relatively small air mass moving beneath and above the panel, while being arranged to limit thermal conduction along the panel is the direction of air flow.  Thus, a thermal gradient is established along the length of the collector panel, with a low temperature differential with the heated air mass at every position, with a fast heating response time, and with re-radiation losses being minimized.  By recirculating the air in a low thermal mass heat exchange system with an energy storage system in such fashion that inlet fluid is at the lowest sus-tatinable temperature, insolation incident upon the collector is more fully utilized.  The thermal energy storage most advan-tageously comprises what may be termed a minimum entropy system, with thermal energy in the heated air mass being interchanged in counterflow relation with a storage fluid which may be fed to different temperature level storages, dependent upon the intensity of the solar radiation available to the collector.
